You can charge an empty battery of your Samsung device in no time with a Samsung Galaxy A51 charger. These chargers are suitable for a lot of older A series devices, like the A51, A50, A40, and A70. These Samsung smartphones all have a USB-C port and support fast charging via Quick Charge or Samsung Adaptive Fast Charging. With such a Samsung A51 or A50 charger, it takes about half an hour to charge your battery for 50%. Without fast charger, that takes 45 minutes. Choose a charger with a cable, or choose a separate charger is you still have a lot of cables. Choose a charger with a sturdy nylon cable if your cables break often.
